>>54386436since you asked so nicely, here you go. beware, it's extremely lewd
https://files.catbox.moe/krkm6k.jpg>>54387093op and i aren't the same person, anon (i'm assuming you were trying to ask drawfag, which is yours truly) but i don't really know what to tell you, i'm not as fast (and talented) as you seem to believe. the only 'advice' i can give you is very mundane: just practice a lot, don't expect to get good right away and don't get discouraged by other people being better than you; the only thing that matters is that you're putting the effort in and improving. also i'm not sure if you mean an 'app' for smartphone/tablet of if you're talking about software in general
